AUXILIARY AIR INTAKE.

I APPLICATION FILED MAY 18. 1916.

I am/thus JOHN w. rnncn'or DUIvKI tK, INDIANA.

- AUXILIARY AIR-INTAKE.

To all wkom it may concern.-

.Be It known that I, JOHN W. FUncE,-a

citizen of the United States, residing at Dunkirk, in the county of Jay and State of Indiana, have invented certain new and useful Improvements in Auxiliary Air-Intakes for Motors; and to be a full, clear, and exact description of the invention, such as will enable others skilled in the art-to which it appertains to i make and use the same.

-. through a My invention which relates to improvementsin accessories for internal combustion engines has for its object to provide simple yet eflicient and durableineans 'for admitting an auxiliary'supply of air into the in take manifold of the motor and for readily compounding such air with the mixture from the carbureter.

With the foregoing general objects in view, the invention resides in certain novel features of construction and in unique com binations of parts to be hereinafter fully described and claimed, the descriptive matter [being supplemented by the accompanying drawings which constitute a part of this application and in which:

igure 1 isa perspective view showing the invention applied;

Fig. 2 is an elevation partly in section of the attaching plate and neck thereof;

Fig. 3 is atop plan view of these parts; Fig. 4 is a vertical transverse section taken on the plane of the line-L4 of Fig. 3;

ig. 5 is a longitudinal sectional view of the valve which controls the auxiliary supply of air; and,

1g. 6 is a vertical transverse section thereof taken on the plane of the line 6-6 of-Fig. 5. In specifically describing the construction shown in the drawings above briefly de- .scr1bed, simi1ar characters are placed on orresponding parts throughout the several views and reference is herein made to the numerous elements by their respective indices. To this end, the numeral 1 designates a flat attaching plate of suitable shape adapted to be clamped between the outlet 2 outlet to the engine cylinders, said plate having formed therecircular opening 5 adapted to register with the outlet 2 and manifold 4. In the present embodiment of the invention, the

Specification of Letters Patent.

I do declare the following .any'dust or the like from said tube 'rugine to which the device Patented July 16, 1918.

. Application filed May 18, 1916.. Serial N 0. 98,413.

plate 1 is substantially elliptical and has notches 6 formed in its ends to receive the machine screws or bolts 7 by which the parts 2 and 4 are secured together.

A tube 8 is formed integrally with the plate 1 and extends radially across the open ng 5 thereof, said tube being perforated and being adapted to admit an auxiliary supply of air into the manifold 4.. To one side of the tube 8 a screen 9 of fine wire or the like is secured in the opening5 by means of a ring 10 as shown most clearly in Fig. 4. The screen 9 is adapted to be interposed between the tube 8 and the manifold 4 and serves not only to prevent the entrance of into the manifold, but effectively breaks up the explosive mixture to render it more volatile.

Theplate 1 is provided with an attaching neck 11 formed integrally with and extending laterally from one of its edges, said neck aving formed therethrough an air port 12 whose inner end communicates with the tube 8 while the outer end. of said port opens through a boss '13 on the free end of the neck. .The neck 11 is disposed in a plane extending obliquely of that in which the plate 1 is locate whereby to position its ree end at a point spaced sufliciently from the carburetor to properly locate a valve casing 14 in respect to the latter and the other parts to be described.

The casing 14 is preferably elongated horizontally as shown and is provided with upper and lower nipples 15 and 16 having alined ports passing therethrough, the upper nipple being equipped with a cut-off valve 17-while the nipple 16 is tapped into the outer end of the port 12. A tube 18 extends from the nipple 16 to a suitable air heater 19 mounted on the exhaust manifold 20 of the is applied. The Mater 19 may be secured in position in any preferred manner but it is preferably provided with a laterally extending flange 19 passage of air therethrough.

he plug 22 is rotatably mounted in a cylindrical socket 23 within plug having a port 24; extending therethe casing 14, said through and registering with peripheral slots 25 formed at diametrically opposite points on the plug, said slots being adapted for registration with the ports of the nip ples 15 and 16 to permit the passage of air '29, the .two plugs 29 and 22 having therein registering sockets in which a coil spring 30 is seated, said spijng serving ,to retain the plug 22 in operi'lti've position unless the plug 29 is removed.

The end of the plug 22 remote from the spring 30 is provided with a cylindrical extension 31 which projects through a cap closing the adjacent end of the casing 14,

the outer end of said extension' il having a crank arm 33 which is connected by a ball joint or the like 3% to one end of a link 35, the other end of this link being equipped with a suitable clamp 36 by means of which it may be secured to the throttle rod 37 of therarbureter 3. The oblique disposition of the neck it properly locates the link 3:) for connection with the rod 37 as will be clearly seen from Fig. 1. this disposition being therefore considered a rat-her salient feature of the invention.

B connecting the link 35 to the rod 37, it will be obvious that the shifting of this rod to control the amount of mixture discharged from the carbureter will simultaneously turn the valve plug 22 to correspondingly control the amount of hot air supplied to the intake manifold 4, thus always insuring that the auxiliary supply of air be in correct pro 'io rtior to the explosive mixture.

From the foregoing, taken in connection with the accompanying drawings, it will be seen that although i have provided an extremely simple and inexpensive device, the same will be highly etlicient and may be readily attached to numerous makes of mo-- tors,.it beingof course understood that the shape of the plate 1 will vary as occasioi: may demand.

in the drawings l have shown certain specific .tails of construction for accomplishing probably the best results and in the foregoing, such details have been described. T will state, however, that within the scope of the invention as claimed, numerous changes may be made without sacrificing any of the advantages thereof.

1. An auxiliary air inlet device comprising a fiat plate for disposition between a carbureter outlet and an intake manifold, said plate having an opening for registration with said manifold and outlet, a vertically disposed perforated tube extending diametrically across said opening, a horizontal arm -oined integrally at one end to the lower e go of said plate aml having a longitudinal air inlet port turned upwardly at its inner end and discharging into the lower end of said tube, the upper end of the latter being closed. and a head on the outer end of said arm having in its upper side an internally threaded socket with which the outer end of said port communicates, said arm extending in a plane at obtuse angles to that in which said plate is disposed to locate its free end in spaced relation to the carburetor to permit attachment of an air valve to said end.

2. An auxiliary air intake device comprising a flat plate for disposition between a.

carbureter outlet and an intake manifold. said plate having formed therethrough an opening for registration with said manifold and outlet, the outlet end of said opening Jll having an annular groove, a perforated tube v xtending diametrically across said opening andspaced toward the inlet end of said openingfrom said groove, a screen between said tube and groove and contacting with the former whereby it is prevented from moving in one direction, a. ring positioned in said groo e for preventing movement of the screen in the other. direction, a horizontally extending arm joined integrally at one end with the lower edge of said plate and hav ing a. horizontal air inlet port with its inner end turned upwardly and discharging into the lower end of said tube, the outer end of said arm having a head formed on its upper side. with an internally threaded socket with which the outer end of said port communicatos, said arm extending horizontally in a plane at an obtuse angle to that of the plate to space the free end of said arm from the carbureter to permit the attachment of an.

air valve. V
